Its not shaking the hole car or anything but you can deff feel theres a vibration. Hope to get this salved. Any help would be great thanks everyone.
I know mustangs and Nissan 300zx Z32 are 2 different beasts. But I had an issue with my 300zx. Had a vibration right up thru the center if the car. Only started at around 25-30mph or higher rpm, vibration felt as if something was out if balance in the drivetrain. Like something was gonna blow apart and leave me stranded.
Turns out, it was the transmission mount. Replaced it, never had another vibration.
But like I said, 2 different beasts.
